to be repaired. Lay in the cloth, then take paper towels and blot and press
out all the excess. The cloth should be pressed down very tight and all the
excess epoxy removed. Otherwise you will add lots of weight very fast.<o:p></o:p></span></p>

<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I replied, but
the lousy email source we are on ate the message I do believe..as there is no
record so I will type it again..</span> <br>

<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Only one photo
opens-call behind canopy and it is blurred, but I think I see the failure.
I will not be able to send any material this week so if you are in a big
hurry (repair this weekend) you can use fiberglass. To repair saturate
the inside core material with epoxy about 1 inch past the damage. Use 3-4 oz
fiberglass and wet lay up over the damage plus 1 inch. So have a 2 inch wide
piece of fiberglass for the repair. After the inside repair cures, try to flex
the area that was damaged...if the damaged area does not flex then you are
done...it is flexes easily then sand and remove all paint and primer. Wet layup
a patch of 2 oz fiberglass on the outside. Fill,feather, prime, paint.</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>What the repair
needs to establish is reinstating the stiffness of the structure. It will
always be much stronger than needed for flight. Stiffnes =good load distribution
and good flight characteristics.<br>
